ToolchainVersion Error

Hello, so I’ve been trying to fix this issue for over a week now, I looked everywhere for a solution but nothing worked. After running “./Setup.sh” and “./GenerateProjectFiles.sh” and trying to do a command “make” it gives me this error: “ERROR: Cannot use an old toolchain (missing ToolchainVersion.txt file, assuming version earlier than v11)”. I tried reinstalling it completely but still nothing, I tried running “rm -rf Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64” and right after “./Setup.sh” but that didn’t work still. I could really use a hand I’m still new to Linux in general.
